a
Clonal growth of D. discoideum was tested on a mixture of K. pneumoniae and P. aeruginosa cells, as described in Fig. 2. +, growth of D. discoideum on the given substrate; −, no growth of D. discoideum.
b
The ability of D. discoideum cells to form plaques was tested on a lawn of pure P. aeruginosa cells as described in the legend to Fig. 3.
